SP EADER,

To all whomcft may concern.

Be it known that I, GEO GE ,VV. VVIL' Liners, a citizen of the United States of America, and resident o-r'M ms, Grundy county, Tll1110lS,.l12tVG invented a certain new and useful Improvement in fSpreaders, of

which the following is a'specification.

My invention relates to an improvement in spreaders-that is, to an improvement in' agricultural implements for spreading ferti lizing' materials over the surface-on the ground.

. ground.

The object of my-invention is to provide a highly improved and efficient machine in which the material is spread evenly and uniformly over the ground, and in which the material being spread is so protectedfrom the wind that it isnot blown or scattered about during the spreading operation, but is.

spread evenly and uniformly over the These andother my invention will be morefclearlyunderstood by having reference to the accompanying drawings, in which I have illustrated my invention in connection with a; straw spreader of the type disclosed in my 'coiending application Serial No. 289,042, filed ipril 10, 1919 .although itw'ill be undertood that my invention is adapted for use n connection with other forms of straw 1 readers or implements for spreading other ertilizing materials. Figure l is a plan view of a spreaderembodying the features of my invention.

' Fig. 2 is a transversesectional view taken on the line e-zor Fig. 1, looking in the direction of the arrows.

i 3 is a longitudinal sectional view. The spreader illustrated consists essenially of a cart mounted on two wheels,10, 'l which. cart is adapted to be hitched to the wagon, in any suitable manner. hiscart comprises a body portion 11, the bottom being formed bymeans of a movable apron 12, provided with a plurality of cross slats 1.3 carrying upwardly projectingpins' or teeth 13 This apron passes around the shaft 17 at its rear end and is driven from the v. l*eels'lO through themediumv of suitable chain and sprocket connections, so that as the cart is drawn forwardly, the apron is revolved so as'to positively feed thermaterial in the cart rearwardly. Mounted intermediate the length of the cart and supported by the sides thereof, there is a cross beam 20 which supportsa plurality of suspending Specification of LettersPatent.

members 21. The upper end of each of these suspending members is hinged to a short horizontal member 22' rigidly secured to the cross beam 20. Thelower. end of each of these suspendingemembers 21 is hinged to the forward end of a reciprocating tooth bar or rake 23. In the con- .struction illustrated, I have shown four of these rakes, but, of course, it will be underrear end thereof,'which crank shaft is provided with a'sprocke't 25, with which a chain 26 engages, this chain likewise passing over a sprocket 27 mounted upon the end of the cross shaft 17. Inthls manner the crank .shaft'isrotated by power derived from the wheels 10, and thus'op'erates to reciprocate the rakes 23 over the traveling conveyer 12' These rakes are so mounted that their. forward ends are slightly lower than their rear 7 ends, and 111 order to ad ust the distance between the forward ends of these rakes and the conveyer 12, to thereby regulate the amount of material being fed through the machine, I' provide suitable means forrocking the cross beam .20. This consists of a hand-lever 28 pivoted at'its lower end to one side of the cart, which lever is provided with a spring tooth engaging the rack 30 for holding the lever in any adjusted po- Rigidly connected to this lever,

there is a short lateral projecting arm 3].

to the end of which a link 32 is pivoted, the. upper end of this link being pivoted to the arm 33 securedto the cross beam 20. By this construction, when the hand lever 28 is moved forwardly, the link 32 moves up-' wardly so as to rock the beam 30 tothereby pullupwardly on the suspending hangers 21, and thus raise the forward ends of the rakes. p

Suspended at the rear of the cart are a pair of rotary heaters or spreaders 3 mounted upon vertically extending rods 35, journaled in bearings 86, carried bysuitable cross bars 37, 38. of these vertical rods is mounted a beveled pinion 39, which meshes with a corresponding bevelpinion 40 mounted upon a transverse. shaft ll. Mounted'upon the end of this shaft, there is a sprocket 42 which is drivenfby means of the sprocket chain 43 which passes over a sprocket 44 mounted upon the end of the crank shaft 24:. With this construction, it will. be seen that. asthe.

cart is drawn forward, the reciprocating rakes23, in combination with the movable" conveyer 12 at the bottom of the cart, operate to feedxt'he material to the rear of the.

cart where it is engaged by the rapidly revolving arms 3l,and thus scattered over the I I surface of the ground.

In. order to protect the 7 material thus scattered by the rotating beaters, and to prevent the wind from engaging the same and whirling it about and thus causing itto ,bewviclely and unevenly, distributed over.

the surfaceof the ground, I provide at the rearof the, machine a protecting hood which completely surrounds the rotating heaters and thoroughly and'efficiently protects the material belng scattered from the action of" the, wind, so that. I am enabled to spread the of ground'of predeterminedwidth.

material evenly and uniformly over a strip This hood consists. essentially of a sheet. of thin sheet meta'l45 shaped substantially in the form. of a half of'a frust-um ofa cone. This .hoodis provided with suitable ribs 46 and issupported at the rear of the implement by means, of two semi circular. hoops 47, a8,

supported at the rear ofthecart, suspending arms 49 extending from the upper hoop 17 to the outer. edge ofthe hood. The forwardends of the hood fit over the sides: of the cart and are secured to the rear ends thereof,

the frontfend of the hood being inclined slightly rearwardly, as indicated in Fig. 1,

to clearthewheels l o and also being inclined downwardly toward the outer edge of the hood,.as clearly shown'inFig. 2; In order to close the-front end of the hood, where it extends outwardly from opposite sidesof the cart, a triangular section 50 is provided on eachside of the cart which extends from the cart to the edge of the hood; These end sectionsare preferably formed by merely bending the front edges of the hood down- 'wardly and operate to close the end ofthe hood where it projectsbeyond the sides of;

the cart, and thus-effectively prevents the wind from engaging the material under the hood. Immediately over the heaters, the

hood is preferably cut away so as to'form a;

' semicircular opening 51 which, when the beaters are being rapidly revolved, permits the air to be drawn. downwardly and then swirled about by the beaters,.a nd thus more effectively distribute the material, If desired, this opening can be omitted,.although I find that better results are-obtained by the use of. same.

It willv thus be seen that my improved hood completely surrounds the rotatingbeaters, terminatingat its inner end in a plane above thebeaters and then inclined down Wardly so'that its outer edge is in a plane below the beaters,. and effectively prevents the wind from engaging the material being scattered by therbeaters, and thus enables this material to'be uniformly distributed T over a strip of ground.

WVhile I have illustrated and, described one particular embodiment of my'inventiom;

and have illustrated same in connection with a straw spreader, itwill be understood that 'I p I do not wish to be limited to suchexact con 7 struction, or to its use in connectionwith a: straw spreaden'as 1t.- will' be obvious that my improved hood may be modified toacer tain extent without departing from the: spirit of my inventiomandlthat'the. same is adapted for use in connecti'onwith spreaders of different types, and that the disclosure of the v straw spreader is merely. forthe pur-. pose of'illustrating' one manner in vwhi'ch 'my invention maybe successfully and effectively 1 ing delivered from said hopper fromithe action ofthe wind.
